Stereoplay Measurement: Sound Enemy No. 1: Jitter

Called inaccuracies in the clock jitter, to German tremors, and distortions on the timeline, you can hear are ultimately.

Digital signals can be transported, transmitter and receiver to the exact same clock must work. Called inaccuracies in the clock jitter, to German tremors, and distortions on the timeline, you can hear are ultimately. HDMI is evolved from the pure image standard DVI computer world. Forcibly put the HDMI audio signal with the clock of the video signal and travels with packets wrapped in the power of images. A sub-optimal from a phonetic perspective technique, from which there is a few ways.

Pioneer uses with PQLS (precision quartz lock system) in the high speed mode of the HDMI standard the backchannel, to establish a communication between HDMI source and sink, so that the two clocks on a more accurate clock agree.

Downside: The sink must also understand PQLS, and currently only two pioneer amplifier, SC LX 71 and 81 (1700 and 2200 euro) can do that. Actually, the CD about PQLS sounds synchronized yet slightly smoother and finer than without. But even without PQLS pioneer tried the HDMI output with a module called P0001 to entjittern, by tracing the shape of the signal and noise free. That acknowledged the BDP LX 91 with a musical flowing, Groovy sound – far away from what simpler BD player so far showed little audiophile characterised.
